TO GLOBE BALL BEARING (10., OF BROOKLYN. NlEl/V N. Y.. ASSIGNOR, BYMESNEuASSIGNMENTS,

YORK, A CORPORATION OF NEW ANTIFRICTION-BEARING.

Application filed January 20, 1911.

. '0 072 TIP/710M it may 1071/1671/ Be it known that I, Cimanas lSumnlunYi-iu. a citizen of the United States, and resident of New Yorkcity. borough ol the Bronx, in the county of New York and State of NewYork, have invented certain new and useful Improvements inAntifriction-llearings, of which the following is a specification.

Mr invention relates to improvements in the class of anti-'l'rictionbearings commonly alled radial, and particularly to such bearings havinga plurality of rows of parallel rolling members, such as balls.

The object of my invention is to distribute the load upon the dill erentrows or series of rolling members and to equalize the load within satelimits ol' elasticity of the metal of the parts. whereby it the loadtends to shift to one series of rolling members it will be automaticillvmore or less distributed to the other series of rolling members. so toequalize or maintain balance oi the load between the several series ofrolling memhers.

ln carrvirre out my invention I provide :1 race having a plurality ofparallel workin; surtaces or grooves and a pluralitv of concentric raceshaving win-king surfaces or grooves alined with the (:(HlLFDOHtllHQgrooves of the first named race. and rolling members interposed betweenthe correspondins: opposed wearing surfaces or grooves. whe ebv theraces are shittahlc latcrallv relatively to one another and the load maybe (qllzlliZfitl and distributed l'ietwcen the races as occasion reoures.

lily invention further comprises novel details o'l improvement andouibinations of parts that will he more lullv hereinatter set forth andthen pointed out in the claims.

Similar numerals of reference indicate correspondiine parts in theseveral views.

The numeral 1 indicates a race or member shown provided with a pluralityof parallel racewa vs or grooves 1, 1 suitably spaced apart. A t 2. 3,are races or members, concentric with race or member 1 and pro videdwith parallel raccways or grooves 2*, 3*, alined with the raceways 1,1". Between the outer and inner races or members and within thecorresponding raceways are rolling .n'iemhers, such as balls 4-. InFigs. 1. 9 and 3 I have shown the races 2. 3, within are 1 andsurrounding a ringdilte part 5 adapted to receive and lit upon a shaftor supporting part (3. while in Figs. 4 and 5 the ring lilte part 5surrounds the races 2, 3, said parts shaft or support 6. Ring 5 isprovided with parallel seats for the races 2, In the arrangement shownthe parallel seats 5, 5" of ring 3 are curved to match thecorrespondingly curved faces 2*. 3 of races 9, Seats 5. 5" are shown soshaped as to provide an intermediate or centrally disposed raised orprotruding portion 5, and the faces 2. 3 of the races 2. 3, arecorrespondingly but reversely shaped. In other Words, it may be saidthat the seats 5. 5 curve in a direction from the edges ol ring 5 sothat the latter is gradually increasing in thickness mward itstransverse center line. while the surfaces 2 3 of races 5),correspondinglfv' curve and have their thinner portions at. theiradjacent edges and their thicker portions at their outer edges. Thearrangement -is such that when the load becomes greater on one series ofhalls than upon an other an equalization will take place owing to theelasticity of the material of the races and the ring 5. and within sal'elimits of su h elasticitv. providing for a large thrust ot the load. andby reason of the curved opposing laws of seals 53. 3 and surfaces 9. 3slight relative movem nt of said parts may take place to case theaction.

The races 2, 3, may he held from lateral movement by any suitable means,such as by the collars T screwed or otherwise held upon shall 6 or asurrounding part and tilted snu rlv ae'ainst the. outer faces of racesS. and the ring :7. B this means the races and ring; will he maintainedin relative positions, and the concentric race or member 1,

surroniuling race 1 which receives.

I nular raceways,

which will be fitted to a hub, shaft or other part, may have limitedlateral movement to ease the work. The balls may be inserted between theraces by forcing them into place under pressure, by means of wellknownnotches in 'the races, or in other suitable manner.

Having now I claim is 2- 1. A double complement radial ball hearingcomprising inner and outer concentric members, each provided with a pairof anand having a double comlement-of balls confined radially andaxially between opposed raceways of the two pairs,- each raceway of onemember being formed complete with both embracing walls in a separateintegral annular raceway piece; said raceway pieces being supported bysaid member, through peripheral faces on the member and raceway piecesthat are curved radially and axially toward the mid-- dle radial planeof the bearing; said memher having a dividing ridge between'its saidcurved supporting surfaces and between the curved circumferential facesof the raceway pieces and providing a separating ridge between saidpieces.

described my invention what 2. A double complement radial ball bear-'ally between. opposed raceways o ing comprising inner and outerconcentric members, each provided with a pair of annular raceways, andhaving a double complement of balls confined radially and axiairs, allof said raceways being formed with their two confining raceways of onemember integral with said member, and each raceway of the other memberbeing formed complete with both embracing walls in a separate integralannular raceway vpiece; sai raceway pieces being supported by said othermember, through peripheral faces on the member and raceway pieces thatare curved radially and axially toward the middle radial plane of thebearing; said member having a dividing ridge between its said curvedsupporting surfaces and between the curved circumferential faces of theraceway pieces and providing aseparating ridge between said pieces.
